Blower door testing may seem complicated and hard to understand, but they are rather simple. The process consists of a powerful variable-speed fan which is temporarily mounted to an exterior doorway of the home. The fan moves air through the house in a controlled fashion, while pressure gages measure the rate of airflow required to maintain a certain pressure. The controlled airflow is used to find specific air leaks in your home. Those leaks not only lead to higher utility bills, but can impact comfort and indoor air quality. An energy audit, including a blower door test can help find those leaks which can be sealed. Hibbs Homes uses the tests as a way of quality control, to insure a well built, tight home. The blower door test can also be used if you're remodeling your home.
